udp_timeout Does Not Take Effect in mixed Inbound Environment

Operating system

Linux

System version

Linux 4.4.302+ (CPU architecture：AMD64)

Installation type

Original sing-box Command Line

If you are using a graphical client, please provide the version of the client.

No response

Version

sing-box version 1.12.16

Environment: go1.25.5 linux/amd64

Description

When using a mixed inbound and setting udp_timeout to 30s, the timeout does not seem to take effect.

With the configuration below, after establishing a UDP connection through the mixed inbound and keeping it idle for more than 30 seconds, the connection is still kept alive and is not closed.

According to the configuration, the UDP session should be closed automatically after being idle for 30 seconds, but in practice this does not happen.

It appears that udp_timeout is not working properly when using the mixed inbound.

Reproduction

Minimal_Configuration.json
command: ./sing-box run -c Minimal_Configuration.json

Minimal_Configuration _client.json
Establish a UDP connection through the mixed inbound with client.

Stop the client sing-box process.

Wait for more than 30 seconds (the configured udp_timeout).

Observe that the UDP session on the server side is still kept alive and is not closed.

Integrity requirements

• I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
• I confirm that I have provided the server and client configuration files and process that can be reproduced locally, instead of a complicated client configuration file that has been stripped of sensitive data.
• I confirm that I have provided the simplest configuration that can be used to reproduce the error I reported, instead of depending on remote servers, TUN, graphical interface clients, or other closed-source software.
• I confirm that I have provided the complete configuration files and logs, rather than just providing parts I think are useful out of confidence in my own intelligence.

Start with Minimal_Configuration.json and the ./sing-box run -c Minimal_Configuration.json reproduction, then trace the mixed inbound UDP path responsible for the configured udp_timeout. Use the client configuration to establish an idle UDP session and verify that the server-side session closes after 30 seconds.
